Puppy security

Hello to all the fur mommy's 🐱🐶

I have a serious but also funny question 🙈

I have a 3 month old female puppy. I am not home for certain hours of the day so I was thinking of a camera?

How can I connect my 1 phone at home with my phone I carry with me to see what she does and so on?

She has her toys and so on with her and I already feel bad leaving her alone 😔because she is all over me and when I leave she cries and I'm not sure for how long she cries for and what she does.

I'm afraid something will happen and she may cry for hours 😢 I'm not sure what she does while I'm away.

So silly question.. How can i connect my 1 phone with my other phone to see what she does and so on? Is it even possible 🤔
